/*
**  Purpose:
**      Edit Dialog procedure for templates with exactly one edit control.
**  Control IDs:
**      The Edit control must have an id of IDC_EDIT1.
**      Pushbuttons recognized are IDC_O, IDC_C, IDC_M, IDC_H, IDC_X, and IDC_B.
**  Initialization:
**      The symbol $(EditTextIn) is used to set the initial text in the Edit
**      control.  It is set to the empty string if the symbol is not found.
**      The symbol $(EditFocus) is used to set what portion of the initial
**      string is selected.  Supported values are 'END' (default), 'ALL', or
**      'START'.
**  Termination:
**      The string in the Edit control is stored in the symbol $(EditTextOut).
**      The id of the Pushbutton (eg IDC_C) which caused termination is
**      converted to a string and stored in the symbol $(ButtonPressed).
